<div class="descr">
<h2 id="details">Detailed Description</h2>
<p>A mouse plugin can be created by subclassing QGenericPlugin and reimplementing the pure virtual <a href="qgenericplugin.html#create">create</a>() function. By exporting the derived class using the <a href="../qtcore/qtplugin.html#Q_PLUGIN_METADATA">Q_PLUGIN_METADATA</a>() macro, The default implementation of the <a href="qgenericpluginfactory.html">QGenericPluginFactory</a> class will automatically detect the plugin and load the driver into the server application at run-time. See <a href="../qtdoc/plugins-howto.html">How to Create Qt Plugins</a> for details.</p>
<p>The json metadata file should contain a list of keys supported by this plugin.</p>

<p>Destroys the plugin.</p>
<p>Note that Qt destroys a plugin automatically when it is no longer used, so there is no need for calling the destructor explicitly.</p>
